Tungsten Copper

This refractory metal composite materials are a combination of tungsten combined with copper or silver.The manufacturing process is to press the refractory, sinter the pressed compact at a high temperature, and infiltrate with copper or silver.copper and its alloys constitute one of the major groups of commercial metals. They are widely used because of their excellent electrical and thermal conductivity, outstanding resistance to corrosion, and ease of fabrication, together with good strength and fatigue resistance. They are generally nonmagnetic.

These series of products are available in accordance with the customers requirments.Please advise details of the specifications attached with your illustrations.
